Time to show resilience (6)
I believe the answer is:
spring
'resilience' is the definition.
(thesaurus)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for spring that I've seen before include "The bouncy season" , "Leap - part of year" , "Start season" , "beginning" , "Vivaldi's work, in order(6;6;6;6)" .)
